Answer 3

Sure, I'd be happy to help you solve the equation 5x^2 - 20 = 0.

To solve this quadratic equation, we need to find the values of x that satisfy the equation. The general form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants.

In your equation, a = 5, b = 0, and c = -20. To find the solutions for x, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

Substitute the values into the formula:

x = (0 ± √(0^2 - 4 * 5 * -20)) / 2 * 5 x = (0 ± √(0 + 400)) / 10 x = (0 ± √400) / 10 x = (0 ± 20) / 10

Now, we have two possible solutions for x:

1. x = (0 + 20) / 10 = 20 / 10 = 2
2. x = (0 - 20) / 10 = -20 / 10 = -2

So, the solutions to the equation 5x^2 - 20 = 0 are x = 2 and x = -2.
